However, in this device, when the device is mounted on a sideways object and lifted while raising the object with a suspension wire, initially, in most cases, the pulling direction of the suspension wire and the suspension lever are used. Since the directions do not match, a lateral load is applied to the suspension lever. On the other hand, the movement and prevention of movement of the slide pin are determined by the rotation angle of the suspension lever. Therefore, considering safety, it is necessary to increase the stroke of the suspension lever tip to increase the play. For this reason, the suspension lever must be formed long. Therefore, the suspension lever has a drawback that it is large and heavy as a whole to withstand a lateral load and to be formed long.

Is in contact with a small-diameter portion on the outer periphery of the cam portion 81, and the horizontal lever 44 is located on the side of the rotary cylinder 63,
Is in a state of being detached from the concave portion 43 of FIG. Further, the slide pin 8 is in a state in which the small-diameter portion 12 comes out of the groove portion 2 and is housed inside the tubular portion 5. Here, the guide piece 24 is located at the tip of the cam groove 13. Further, the pin 25 shown in FIG.

The operator inserts, for example, a part of a steel column 86 for construction into the groove 2 of the device in such a state,
The hole 87 and the hole 7 of the main body 3 are aligned with each other, and the spring outer cylinder 16 is rotated in the direction of arrow B by hand. At this time, the operation of rotating the spring outer cylinder 16 is performed against the force of the spiral spring 23. Here, one end 36 of the lock lever 33 slides on the outer periphery of the spring outer cylinder 16.

When the outer cylinder 16 rotates in the direction of arrow B in FIG. 3, the slide pin 8 is guided by the guide piece 24 and the pin 25 as shown in FIG. When the one end 36 of the safety lever 35 and the recess 32 of the spring outer cylinder 16 engage, the state shown in FIGS. 4A and 4B is obtained. That is, the small diameter portion 12 of the slide pin 8
Is inserted into the hole 87, and the spring outer cylinder 1
6 is locked by engaging the one end 36 of the safety lever 35 with the concave portion 32. At this time, the guide piece 24 is located at the rearmost end of the cam groove 13. A pin 25 provided on the frame body 1 shown in FIG.

At this time, since the suspension lever 71 is always in the same state as the pulling direction of the suspension wire, it does not receive a lateral load. When the steel column 86 is lifted and completely separated from the ground, the present apparatus is in the state shown in FIG. Even in this state, the spring outer cylinder 16 is still locked by the lock lever 33.
And the safety lever 35 is doubly locked to the main body frame 1 by two levers.

Next, the steel column 86 is carried to a desired position,
When the suspension wire is loosened while maintaining the upright state, the suspension lever 71 rotates in the direction of arrow A in FIG. 1 due to the urging force of the spiral spring 73 and the weight of the projection 83. As a result, the rod 65 moves upward, and the relationship between the concave portion 43 of the lock lever 33 and the lateral lever 44 is again as shown in FIG. Therefore, the lock lever 33 is free to rotate in the direction opposite to the direction of arrow C shown in FIG. 4B.

Next, the worker checks the safety and checks the rope 57.
When the lever is pulled, the engagement between the safety lever 35 and the spring outer cylinder 16 is released, so that the spring outer cylinder 16 is rotated by the urging force of the spiral spring 23, and the small-diameter portion 12 of the slide pin 8 is moved toward the cylindrical portion 5 side. When retracted, the device can be removed from the steel column 86.

According to the present embodiment, in the frame body 1, the rod 65 is provided coaxially with the rotary cylinder 63, and the slide pin 8 is locked and unlocked based on the axial movement of the rod 65. Therefore, locking and unlocking can be reliably performed regardless of the rotational position of the rotary cylinder 63 with respect to the frame body 1 at any position.

According to the present embodiment, the spring outer cylinder 16 can be locked by the safety lever 35 alone. Therefore, when the present apparatus is mounted on the reinforced pillar 86, the spring outer cylinder 16 is rotated against the urging force of the spiral spring 23, and the spring outer cylinder 16 is returned with the slide pin 8 inserted through the hole 87. Rotation can be prevented. This eliminates the need for the operator to wait for the lifting lever 71 to rise until the spring outer cylinder 16 is locked by the lock lever 33, thereby facilitating the mounting operation.

On the other hand, when the reinforcing rod 86 is lifted, the spring outer cylinder 16 is prevented from rotating by both the lock lever 33 and the safety lever 35. For this reason, even if the suspension wire is loosened, the spring outer cylinder 16 is locked by the safety lever 35 and the rope 5
Even if 7 is pulled by something, the spring outer cylinder 16 is locked by the lock lever 33. If one of the lock lever 33 and the safety lever 35 holds the spring outer cylinder 16 in the locked state, the other automatically returns to the unlocked state even if the other is temporarily in the unlocked state. Therefore, according to the present apparatus, the steel column 86 can be lifted and transported safely and reliably.

According to the present embodiment, since the mark 84 is provided near the tip of the suspension lever 71, the operator can know in which direction the suspension lever 71 rotates, and the operation of the present apparatus is easy. Sex and work safety can be increased.

In this embodiment, a steel column for construction has been described as an example of an object to be suspended. However, any object can be used as long as it is partially inserted into the groove 2 of the apparatus and can be locked by the slide pin 8. Well, the device can be used in a similar manner.

In the present embodiment, the one end 36 of the safety lever 35 is always locked in the recess 32 of the spring outer cylinder 16.
May be provided. If this mechanism is used, no manual operation is required when removing the apparatus from the object to be suspended.

[0047]

According to the first aspect of the present invention, since the longitudinal direction of the suspension lever and the tension direction of the suspension wire are the same, only the tension load is applied to the suspension lever, and the lateral load is not applied. Absent. For this reason, the suspension lever can be made thinner or thinner, so that the weight can be reduced, and the weight of the entire apparatus can be reduced.

Further, the effect of eliminating the twist of the suspension wire can be obtained. This is particularly effective when a plurality of the present apparatuses are used by being attached to a suspended object.

Further , according to the first aspect of the present invention, the movement of the slide pin can be reliably locked in accordance with the state of the suspension lever with a simple configuration.

According to the second aspect of the present invention, since the movable portion of the moving mechanism for moving the slide pin can be reduced, the size of the entire apparatus can be reduced. In addition, it is possible to reduce the chance that the movable portion comes into contact with an external object and hinder the operation, thereby stabilizing the operation.
